VALVE.

Specification of Letters Patent. Patented Sept. llll, 191% Applicationfiled June 3, 1915. Serial No. 32,021.

To all whom it may concern:

Be it known that I, HUGH P. BRUNK, a citizen of the United States,residing at Sylvia, in the county of Raleigh, State of est Virginia,have invented certain new and useful Improvements in Valves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The present invention is directed to improvements in valves, and has forits objcct to so construct a device of this charactcr that the flow offluid may be discharged from a pair of spaced ports, or the valve may beregulated to discharge from a single port, said valve being operable tocut off the flow from all ports.

A further object of the invention is to provide a novel means forindicating the discharge ports.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure 1 is a side elevation ofthe valve.

Fig. 2 is a top plan view.

Fig. 3 is a vertical sectional view through the device.

Fig. 4: is a transverse sectional view.

Referring to the drawing 1 indicates the casing, having the seat 2formed therein and communicating with the seat 2 are ports 3, 4 and 5,any one of which may be used as the inlet port.

The top of the casing 1 is provided with an opening 6 in which isengaged the stem 7 of the plug 8, said plug being rotatably associatedwith the seat 2 and is provided with radial communicating passages 9, 10and 11.

A cap 12 is provided and serves to close the lower end of the seatfZ,said cap having a flange 18, and by which the cap is attached to thecasing.

Mounted on the stem 7 is a head 14:, said head having a vertical bore 15formed therein which is provided with an annular shoul der 16, which isengaged by the upper end of the coil spring 17. The coil spring 17encircles the stem 7 and has its lower end resting upon the top of thecasing 1, said spring serving to hold the top of the plug 8 in bindingengagement with the inner surface of the top of the casing, therebyeliminating the necessity of using a packing or stufiing box.

The head 15% is so fashioned as to provide points 18, which serve asmeans to indicate that the desired ports are in communication with thedesired passages. It will be noted that when a point 18 is alined witheach port that all passages will then be in registry with the ports.

From the foregoing description it will be seen that a valve casing hasbeen provided so constructed that the use of threaded con-- nections areeliminated.

What is claimed is A valve comprising a casing, a seat in the casing, aplug rotatable in the seat and having radial communicating passages,ports formed in the casing and adapted tocommunicate with the passagesupon rotation of the plug, a stem carried by the plug and eX- tendingthrough the top of the casing, a head fixed to the stem, said headhaving an annular shoulder formed therein and its outer face providedwith a plurality of angular surfaces, certain adjacent edges of whichintersect to form pointers movable on the upper surface of said casing,a coil spring encircling the stem and having its upper end engaged withthe shoulder and its lower end engaged with the top of the cars ing,said head having a plurality of points thereon which are adapted toaline with the ports to indicate which passages are in registry with theports, said spring serving to hold the top of the plug in yieldableengage ment with the inner surface of the top of the casing, and theheadin yielding adjusted position.

In testimony whereof, I ailix my signature, in the presence of twowitnesses.

HUGH P. BRUNK.
